To all whom it may concern.'

Be it known that I, JOHN K. KorcHUK, a citizen of Ukraine, residing at Melville, in the Province of Saskatchewan and Dominion of Canada, have invented certain new and useful Improvements in Grain-Doors,

`of which the following is a specification.

This invention relates to certain new and useful improvements in grain doors.

The primary object of the present invention resides in the provision of a door especially designed for grain car bins or the like wherein the door is formed of a plurality of sliding shutter sections and moving from opposite sides of a door opening toward the center thereof to provide a complete closure for the opening.

A further object of the invention is to provide a grain door formed of a plurality of shutter sections slidably associated with each other and divided on a horizontal line to provide independently operable upper and lower sections. i

A still further object of the invention includes the provision of locking arms associated with the shutter door sections to prevent the sections from being opened when the locking arms are in their operative p0- sitions. j

With the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views,

Figure 1 is a front elevational view of a door and frame therefor constructed in accordance with the present invention, one of the upper door sections being moved to its open position,

Fig. 2 is a horizontal sectional view taken on line II-II of Fig. 1 showing the sliding door panels moved to their closed position relative to the door opening with the locking arms in their positions,

Fig. 3 is a vertical sectional view taken on line III-III of Fig. 1,

Fig. 4 is a vertical sectional view similar to Fig. 3 with the door sections removed and the locking arms in their folded inoperative positions,

' Fig. 5 is a detail sectional view tekenen `tion to line V-V of Fig. 6, showing two of the door panel sections slid to their extended positions,

Fig. 6 is a f ront elevational view of a pair of p anel sections, with one of said panels partially broken away, and

lgs. 7 and 8 are perspective views of the lower and upper door panels, respectively.

Referring more in detail to the accompanying drawings, and particularly to Figs. 1 and 2 there is illustrated a frame structure 1 representing a car side silo wall or binz having a door opening therein defining a sill 2 and an upper rail 3 with the side walls thereof constructed in channel formaprovide vertical side pockets 4 having entrance openings 5 thereof.

The door construction embodies a plurality of panels slidably mounted upon each other as illustrated in Figs. 1 and 2 for housing within the pockets 4 when the same are moved to their open position, the panels being divided upon a horizontal line to provide lower sections 7 and upper sections 8, two of the upper panel sections 8 being shown in detail in Figs. 5 and 6, the lower and upper panels 7 and 8 having recesses 9 formed in one face thereof and covered by plates 10 that are slotted as at 11 for purposes presently to appear. The outer faces of the panels 7 and 8 are provided with the recesses 9 and slotted plates 10 and the panels are assembled in sliding relation similar to a camera shutter, the rear face of one panel slidably engaging the front face of the adjacent panel while headed pins 12 as shown in Fig. 5 are carried by the rear face of each recesses 9 through the plate openings 11, thus locking the adjacent lower panels 7 and the adjacent upper panels 8 in sliding engagement with each other. The engagement between the upper and lower panels 8 and 7 includes the provision of a cutaway portion 13 upon the upper edge of each lower panel 7 and the provision of a depending plate 14 upon the lower end of each panel 8 with the plate riding in the cutaway portion 13 as clearly shown in Figs. 1 and 3. The upper and lower forward end panels 8 and 7 are fixed to the forward wall of the pocket 4 and the panels when in their extended position are arranged at an angle relative to the transverse axis of the door opening while the outwardly-extending panels .7 an

in the inner walls 6y panel and extend into the panel 8 Vat one side of the door are provided withv gaging the opposite door panel sections to retain the doors in their closed position as shown in Figs. 1 and 2.

A locking device for retaining the door panels closed as illustrated in Figs. and 2 embodies a pair ot locking arms 17 hingedly mounted at their lower ends as at 18 upon the inner walls of the 'Dockets l as'shoivn in Fig. Il, the arms 1i" having hinge extern sions 19 lwith hooks 2O at the tree ends thereoli for engagement With each other When the arms are moved to their locking position as shown in Fig. 2.v A pairot arms 17 isvmounted-Within each housing e] adiacent the upper and loiver ends ther-eci2 tor securing the lower and upper closed panel sections 7 and 8 in their locked position. VThe 'forward edges of the arms 1? and extensions 19V are inclined as at 21 and substantially contact the panel sections over the entire lengths thereof: so that sliding move- Y ment oi1 the panel sections will be prevented when the'locking arms are in the horizontal'V position shown in Fig. 2.

To open the door from the position shown ,in Fig. 2 the engaging ends 2O of the arm extensions 19 are tree to permit the eXtensions'to fold upon their hinge connections with the arms 17, after which trie arms are moved Within the housing' 4: upon their hinged ends 18, whereupon the panel hooks 15 and 16 are released to permit the panel sections to slide uponV each other and bek guided by the pin andslot connections 12 and 11 to enter the opening 5 in the pocket l and provide an unrestricted passage through the door opeing. lWith this construction ot door, the openingV theretor may; vbe regulated by shitting any of the door sections, as b v opening one of lie upper sections as shown in Fig. 1 or either of thelov/er sections without disturbing the remaining.. Astructur An advantage is present in the Y Viactthat the locking device for the door panels is fastened to the door trame andV when the door is in its open position the locking devices are hidden from view which will prevent tampering` with the same.

While there is herein shown and described .thepreferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope ot the invention-as claimed.

What is'claimed as new is 1. A grain door of the ltype described comprisingin combination with a door opening having` frame pockets at opposite sides thereof, a door formed of sliding panels adapted to extend across the door opening when ,in closed position and to -be -received vin said pockets when in open posithe path of opening movement of the panels to hold the same Vin closed position.
